Does GPL classpath exception apply for "fat jar" contianing all JAR files or do I have to redistribute source?

Question

I am reading here: http://www.gnu.org/software/classpath/license.html

for http://www.jidesoft.com/products/oss.htm

I would like to keep a single JAR file if possible for everything.

Thank you Misha

p.s. Alternately, is there a good, cross-platform (Windows & Mac) way to deploy multi-jar files without Java Web Start (I need it to run as a system service as well, and I'm not sure JWS will let me). Thank you!
